VASCM: Grapevine Health Check

[Prudy Foxx]

Hi!
FYI:
Many of you have contacted me over the years with concerns about virus and fungal disease that may be affecting your vines.
While many diseases can be diagnosed by observation, some, especially viruses, must confirm detection through a lab sample.  Often these samples are best taken this time of year.
If you have concerns about symptoms of virus in your vineyard now is a good time to take a sample and send it in.  This is one lab to use.  There are other excellent labs available.  This is one choice.  
Have a great season!

Protect Your Grapevines during the Harvest Season with HealthCheck™ Panel A
Best wishes for the upcoming Harvest Season from Eurofins STA!  Now is the best time to defend your grapevines from this season’s common viruses by using HealthCheck™ Panel A Testing!  

HealthCheck™ Panel A includes ELISA and RT-PCR detection of GVA, GVB, GVD, GFkV, GLRaV 1-7, & -9 (includes GLRaV-2 RG) , RSPaV, RSPaV-Sy, GSyV-1. 

Samples can be collected either from actively growing vines during the growing season from September through December, or from dormant vines.  We recommend providing one representative sample consisting of portions of canes, cordon, or trunk (6-8”) from each vine.  This is important to ensure the best detection of infections and prevent the possible spread to the rest of the vineyard.  The cane material should be collected from the basal portion of the vine (i.e., older growth).  If leaves are present, please provide a representative sample portion of this also, for symptom tracking.  INSIDE TIP:  Our research has shown that higher concentrations of viruses associated with Leafroll and Rugose Wood Complex diseases are found most commonly in the mature portions of the vine.

It is still very beneficial to continue monitoring your grapevines with the HealthCheck™ Fungal Panel during this time of the year!
